I myself have sat in on several discussions that point out that the REASON we have an ad hoc, community based approach to addressing racism and servers created for the purposes of doing racism, pretty much comes down to the very poor moderation tools available to work with. Maybe talking about how they don't work at solving the problem, is part of how we get someplace better? How do you know? You certainly won't ever find out telling folks attacked by racists that it's their fault.
